4. Attach the electrostatic discharge (ESD) wrist strap. Your system has an ESD jack on the front and on
the rear of the system as shown in the following figure. Plug the ESD wrist strap into the ESD jack.
Attention:
• Attach an electrostatic discharge (ESD) wrist strap to the front ESD jack, to the rear ESD jack,
or to an unpainted metal surface of your hardware to prevent the electrostatic discharge from
damaging your hardware.
• When you use an ESD wrist strap, follow all electrical safety procedures. An ESD wrist strap is
used for static control. It does not increase or decrease your risk of receiving electric shock
when using or working on electrical equipment.
